Water Supply System

The Burj Khalifa’s water system supplies an average of 946,000 l (250,000 US gal) of water per day through 100 km (62 mi) of pipes.  An additional 213 km (132 mi) of piping serves the fire emergency system, and 34 km (21 mi) supplies chilled water for the air conditioning system.

Air Conditioning

The air conditioning system draws air from the upper floors where the air is cooler and cleaner than on the ground. At peak cooling times, the tower’s cooling is equivalent to that provided by 13,000 t (29,000,000 lb) of melting ice in one day.[66] The condensate collection system, which uses the hot and humid outside air, combined with the cooling requirements of the building, results in a significant amount of condensation of moisture from the air. The condensed water is collected and drained into a holding tank located in the basement car park; this water is then pumped into the site irrigation system for use on the Burj Khalifa park.
